I' r5I mechanism, function as lasting means.

The objects of the invention are to render possiblefthe lasting of a shoe on a single machine; to provide a lasting machine of greater size range than has heretofore been'available; to provide v a lasting machine requiring a minimum of shoe handling; to speed up production; to minimize production costs; to afford perfection in lasting; and to provide the various other advantages and results made evident fromv the following specifi- 1'5 cation. f

The machine embodies a toe portion wire wiping mechanism and a pair of side wipers which function to last a shoe at the shank and heel portions, and hold the shoe in place upon the '20S jack while the wire wiper functions'at the sole and toe portions of the shoe, together with operating means. f

I attainthe objects of. the invention Aas shown in theaccompanying drawings which form a part .2'5 of this .specification and in which similar Aletters of reference refer to similar parts throughout the various views. The shoe is rst prepared for the lasting operation by assembling the upper. and insole upon a last and applying to the exposed '30, portion of the insole and the adjacent portions of the upper a suitable coating of cement or other suitable adhesive which is allowed to dry. VThe last with the upper thereon is then placed upon the jack of the machine, hereinafter more par- 'j ticularly described.

It will be understood that said assembling includes the temporary placing of suicient lasting tacks to hold the shoe upper as assembled. E

In the drawings, Figure 1 is a partial plan view 240'; looking down upon the machine, with the side wipers and wire wiping mechanism in open position, and an assembled shoe in position upon the jack ready to be lasted. Figure 2 is a sectional side view taken on line 2-2 in Figure 1 except '451 that the side wipers areshown clamped onto the shoe in a closed position and the mechanism which operates the side wipers is but partially shown. Figure 3 is a sectional View taken on line 3 3 in Figure 2, and shows the side wipers v in closed position. Figure 4 shows a sectional View similar to Figure 3 except that the side wipers are in an open position. FigureV 5 is an enlarged plan view of one of the wirev wiping` mechanisms.- Figure 6 is aside View` of the mechanism shown in Figure 5. Figure 7 is a sectional view on line 7--7 in Figure 1, showing the guiding and swinging construction of the wire wiper arms. Figure 8 is a plan view showing the side wipers in partially closed position with the wiper wire in contact with the toe of the shoe, a part of the upper being lapped over the wire and held in such lapped position by means of a clamp. Figure 9 simulates Figure 8 with the wire wiper in closed position about the sole. Figure 10 is a fragmentary longitudinal sectional View taken through the forward part of the last as shown in Figure Sil-showing the operation of the clamp which holds in lapped position the lapped portion of the upper with the wire therebetween.

Referring again to the drawings, A shows the frame upon which the machine is built. B1 and B2 show side wipers mounted upon and operated by the cam arms D1 and D2, which are held in operating position and slide between the guides C1, C2, C3 and C4. The cam rolls El'and E2 are 75 mounted upon the guides C1, C2, C3, and C4 by the studs E3 and E@ The springs Fl and F2 hold the cam arms D1 and D2 against the cam rolls El and E2 and tend to maintain the side wipers in open position as shown in Figure 4. 8O When downward pressure is applied to the connection H (by means of a foot treadle or a power operated mechanism) the cam pivoting block G secured thereto moves downward, whereupon the cam arms D1 and D2 secured to the block G at 85 G1 and G2, operate against the cam rolls El and E2 and move the side wipers B1 and B2 to closed position.

A shoe J is shown on a last 1 which in turn is mounted upon the jack K. The jack is adjustable by means of the adjusting sleeve L and the spring M so as to allow the last to yield under pressure. The rod N and the nuts O and O1 function to adjust the tension of the spring M. The toe of the shoe is supported by a yielding' 95 pad P, adjustable by means of an adjusting sleeve Q, and the spring R so as to allow the pad P to yield under pressure; the tension of the spring R is adjustable by means of the rod S, and the l nuts T and T1. The back rest U pivots upon the pin U1 on the frame A and is adjustable to any desired position by means of the set screw U2. The back rest is designed to avoid slipping of the shoe when the side wipers are not used or when otherwise required.

The wiper mechanism comprises preferably a strong spring tempered wire V (but any suitable wire or other substance capable of standing the strain may be used) maintained under ten sion by means of two springs V1 and'V2 over and 11p upper on the last, and means for moving the around the toothed rolls V3 and V4 which in conjunction with the wire help to wipe the forepart of the shoe and which are mounted on and revolve on the studs V6 and V7, between the wire wiper arms W1, W3, W3, and W4, which are in pairs and slide in the swinging brackets W8 and W9 held in position by means of the spring W5. As the arms advance into the so called closed position, the toothed rolls V3 and V4 following the of the sole of the shoe, cause the arms W1, W2, W3, and W4 to open and allow the toe of the shoe to pass therebetween as shown in Figure S. The rolls W6 and W" t into and slide in the slots Y1 and Y2 in the sliding bracket Y, and allow the arms W1 and W3 to move into a relatively parallel position as the bracket Y is pulled forward by means of the flexible con nection Y3, passing over the roll Y8 pivoted on the stud YQ on the frame A, and operated by a foot treadle or power mechanism. The tension of the spring Y4, secured to the pin YG in the frame A and the pin V5 on the slide Y, brings the sliding bracket Y backward to its original position when the pressure is released on the iiexible connection Y3. As the sliding bracket Y travels forward, the wire of the Wiper arms mounted thereon likewise moves forward to function together with the help of the toothed rolls in the wiping and complete lasting of the toe and forward portion of the shoe.

Only one arm is shown in Figures 5 and 6, but it will be understood that both arms are of similar construction. The rolls V3 and V4 are likewise identical for which reason V4 only is shown. The rolls V3 and V4 are grooved at V8 to afford a proper guide for the wiping wire, and are iianged and toothed at V5 to provide means for forcing the upper over the sole as the wiper wire moves forward. As the wiper wire is brought onto the toe, a portion of the upper Z (see Figure 10) is lapped over the wire V and held in lapped position by the clamp X, mounted on the frame A by the pin X1, and is held in clamping vposition by a spring X2. After the portion Z of the upper is lapped at the toe and secured in lapped position by the clamp X, the wiper wire is moved into closed position as shown in Figure 9, and together with the toothed rolls as described completes the lasting operation at the fore portion of the shoe.

The spring V2 is adjustably mounted by fastening the spring to an eye bolt V11 with the nut V12. Tension is supplied by loosening or tightening the nut V12 (see Figures 5 and 6).
